Don't waste your money on cheap backpacks; I did and regretted it. I bought this to replace a cheaper (non-CamelBak) water backpack we bought 2 years ago. It was a pain from the start: hard to clean, mouthpiece leaked frequently, etc. The final straw was when the mouthpiece cracked while climbing a mountain with my son - this is where the water bladder failures are worst! We've had a smaller one for years and never had any issues, so this time I'm paying for the quality we need. We have used this backpack several times and it works great.
Bellissimo zaino comodo e funzionale. Sicuramente non economico ma la qualità percepita è assolutamente alta! Ottimo compromesso tra leggerezza e capienza.
